Let us just get it out of the way and list the ways you can use The Blue Spiral G.
Harness
Temperature play
Anal
Vaginal
This product can be used with a harness while the harness ring fits the circumference of this product. Which can be found in Design, Shape, Size section. You can still use your hand or partners hand.

Next is temperature play; now this can be tricky if you don't know what your doing. When using temperature play and wanting to get this item warm, just hold it under the sink and run warm water over The Blue Spiral G.
Another way is to warm up a bowl of water. Please note not to get water boiling; you can burn yourself. Just hot to were you can place a hand in the water and not bother you. Then place in the product to warm up. Still there is cold; the easy way is hold it and run cold water over this product or put the item in the freezer for 5 minutes. To get cold, still in bowl you place cold water, ice cubes, and this product.

Yes, you can use this anal or vaginal. Please note that too much trusting power can cause bruising in the area. If that happens, stop doing anything sexual for few days to week in that area; to give time to heal.

If your someone that's into anal or vaginal play that would like to try harness play or temperature play, this product is perfect for you. Also, if you have allergies this is a very safe product.

The Blue Spiral G is made out of Pyrex. What is that? Well, it is the glass that you can heat up and freeze. First used for borosilicate glass some time in the 1940's but was first made in 1915. This type of glass is very strong. So most likely you're not going to break it and it is not flexible. Hell, the day I got mine I drop it down stairs and nothing. Over the years I've dropped it thousands of times and still nothing. It looks just as good as the day I got it. Sadly when it does break, it will be in maybe two or three pieces. Some times more but always big pieces. Pyrex is easy to clean.

Pyrex is very smooth and has no taste or smell to it if cleaned the right way.

This item is very safe. This is made out Pyrex so latex free, phthalates free and non-porous. Plus you should know that if you have allergies, this product is hypoallergenic. That's one main reason I tried Pyrex products.

Now this product is clear with blue bumps. The length of The Blue G is 7.25 inches from tip to base. Which is about two packs cigarettes long. Now the circumference is 4.75 inches and about size of female fist. Now this weighs 10 and half ounces which is a can of soda pop a little more than half way filled. At first glace you might think this product is straight but it has a curve to it.

For average user this product is a good size, not too big but not to small.
If you can find place to hide this product in suitcase, handbag, briefcase, etc this is great to travel with.

Note that this product has bumps on the shaft. This does help the product in anal or vaginal area. How? Bumps are spaced out to the rhythm that we all know. That rhythm of opening wider and then to a normal size and so on can give the feel of the real thing. This combined with the shaft at a slight curve that helps hit the g-spot for women, makes this product great for the average product user. I also find that rubbing the shaft from clitoris hood to the labia and back is one way to enjoy The Blue Spiral G design.

If you use the Blue Spiral G by hand or harness, you will find that it can be very powerful. Even without have vibration. You can tease your partner by giving this dildo a good old blow job, licking it etc. Though this product is only a dildo there is so much you can do. In temperature play I like it cold for vaginal and room temperature for anal. With any lubrication you will find this product easier to use, which I think is needed for anal. Again, watch the trusting power that you use; can cause some bruising. For the most part you will be screaming with delight when you're using this product.
What I love about the flared base is that it is a good base. You can stand the product up and it will not tilt over. It is what makes this able to be use with a harness; plus anal and vaginal safer.

There is so many ways to clean this product. A 10% bleach to 90% water; let it sit in the mixture for three minutes, water and antibacterial soap, boil some water and boil for three minutes, bleach wipes, dishwasher, toy cleaner, antibacterial wipes, etc. The Blue Spiral is one of the easiest toys to clean that I have owned.
Remember to clean before and after each use and when sharing; please be safe and use a different condom each time.
I keep this product in my dresser in its bag.
Please take note; never to place in microwave. It can be on too long and cause it to break once it cools down. Lubrication can be used and can be need. Luckily you can use any, but I find silicone to be the best.

I have owned this product for a bit now and can tell you Pyrex is also known as e-glass. How it got that name I can not tell you. I found only adult shop owner that know it by this name. If you have very little money, this product for e-glass is cheap and is worth it. Stop buying toys that break in a month and start buying toys that are worth every penny, like this one.
